To all wltrmt it may concern:

Be it known that I, JEAN SCHMIDT, a subjectof the Emperor of Germany, and a rcsl dent of 3 Kaiserstrasse, Frankfort-on-the- Main, Germany, have invented 'certain new and useful Improvements in Photographing, of. which the following is a specificatiom' This invention relates to a'process of tak ing photographs, and has forits object to produce a photograph having'very soft tones and to avoid undesirable shadows; and to these ends the processconsists in exposing the ob- .ject to be photographed successively to three lights of various strengths and'actinic effects.

In carrying out-the process the object to be photographed is exposed to a relatively feeble light of little or no actinic effect, which 7 is preferably a reflected light from incandescent illuminated lamps, and in this light the object is posed so as to produce the desired effects. The object is then subjected toa powerful white light of considerable actinic effect, such as may be produced by overcharging incandesc'ent lights, and the object is finally subjected to a strong instantaneous light of great actinic effect. These various effects thus successively produced result in producing'a photograph without undesirable shadows and of very soft tones, and especially when these successive lights of various intensities are reflected from one reflector it is possible to so expose the object to the first light as to get\the required or desired results of light and shadow and then by means of the successive stronger and more actinic lights to produce the effects desired.

In the accompanying drawing there is illustrated one means of carrying out the process constituting the invention.

For this purpose the device is so made that a shade or screen A, with reflective surface turned toward the person or object to be .pho-

.tographed, is provided with incandescent conducting material are placed opposite each other in the center of the shade or s reen.

These contacts lie in a powerfnl elect ric cir' cuit,--which canalso be conducted through 'the incandescent lamps arranged all around F the shades or screens, and are so arranged that they can be separated from each other at'any'momentdesired by means of an elec- 'tromagnet D,'and a stronginterrupting-spark of extremely great acfinic etfect thus passes from one contact to the other. This contact apparatus is alsoieparated from the object to be photographed by means of a shade or screen E in such a mannenthat it throws its light toward the tter and from there onto the object to be I uniin'ated. The arrange men}; is cpunected with'a circuit-changer'or switch and is arranged in any known manner,

so that, on the onehand, acurrent is passed throsgh the incandescent lamps B, arranged around the contact apparatus, of an intensity sufiiciently great for their ordinary working, and, on the other band, also momentarily allows a strong current to pass into the circuit of said lamps'and again out of it and then at.

the same time or at the next moment'passes through the two contacts, which are simultaneouslyseparated from each other by means of an electromagnet D, and then the'interrup ing-spaik of actinic eifectis produced. In this manner the object-to be photographed is exposed to three lights of various strengths that is,- first to tlielight reflected by tfieshade or screen of the incandescent lamps supplied with their ordinary current. In this light the photographer is able to place the object to be photographed in the desired light, which he can do very easily and with the greatest accuracy by moving the shade, as the beams, which later on have an actinic effect, fall upon the object to be illuminated exactly in the same direction as those which only illuminate. When the object has thus been placed in the correct position and light,'a powerful current is passed through the incandescent lamps by means of the circuit-changer. These lamps are overcharged, and consequently now throw a white light of actinic elfect toward the shade or screen, which light, the objective now being open, introducesgthe photograph, which at the following moment is completed through the immediate separation of the contacts and through the interrupting-spark prol posing theobjetat to-l which magnet shortly before thponferfu The shetdes orIscreens-G and 1 inferrnpting-sparltf mm3 -;1m tographed; are .transperen notithrow s'any.nndesireb Iclainpi eEsi AVAllLABLE cote I fleece a (.iuced thereby Through the hicrcasing ef i feet of the light described the photograph re-l} ccives very soft tones, &c.', j:mul by means 0R sively to three lights of various strengths and actinic effects.
